BEARING-ASSEMBLY.

Application filed April 30, 1918.

To all 'whom t may concern:

Be it known that I, EARL H. SHnRnoNDY, a citizen of the Uni-ted States, .residing at Cleveland, `in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Bearing-Assembly, (Case QI.) of which the' following is a specification.

This invention relates to a bearing assembly, more Aparticularly to a bearing assembly for use' in connection with the bearings of a turbo-compressor, which comprises the usual turbine wheel and compressor Wheel mounted on the same shaft. I

It issn object of the invention to provide a bearing assembly which may be readily positioned in place in the casting, forming the ymain parts of the turbo-compressorunit. -it is of importance in rapidity and cheapness of production to have these main castings in one piece, and the' bearing assembly of this invention is designed to permit of mounting the bearings and housings in' said castings, Without splitting the castings.

@their objects and advantages willl appear as the description proceeds.

In the drawings, Figure 1 is a side View, parte being broken away and shown in sections of a turbo-.compressor unit and the bearing assembled in position; Fig. 2 is a section on the line. 2- 2 of Fig. 1; Fig. 3 is a section on the line 3--3; Fig. 4;'. is a plan` View of ythe upper half of the beating housing shown at the right of Fig. 1, and Fig.

5 is a View of a modification in' which the thrust bearing is located on the opposite end 'of the shaft.

Referring more particularly to the drawings, turbo-compressor comprises the .turbine Wheel 1 and the blower Wheel 2,

virnounted on the common shaft 3. The turbine casing is indicated at 4, and theblower easing atb.'v The details of these Casings and the means of operating the turbine form no part of this invention, and need not be described;

The front Wall 7 of the blower' casing is cast integrally with the flaring mouth 8, for the ingress of the air to the wheel 2. The casing 9 for the bearing housing is eastV integral with the iiaring mouth 8, and front wall 7 of the blower casing, and is supported by a series of curved blades l0, cast integral with parts 7, 8 and 9. The arrangement, of these blades is particularly described in my copending case Serial No'. 231,767 `filed Specification of Letters Patent. A

Patented July 22, semi N. 231,766.

April 30, 1918. The end 11 ofthe sl is mounted in .bearing 12, which nr se provided with the usual spherical seat'13, 14 represents a thin layer of ba'bbitt. Bearing 12 is provided with an oil hole 15. ing 12 is not split, being preferably made in one piece.

Arranged around bearing 12 is the split housing 1G, provided with the usual spherically curved concave seat for the spherical part 13 for the bearing 12. The split 'seetion of the housing 16 may be held together by a ring 17. A 'pin 18, located in suitable recesses in the housing and bearing keys of thesetwo elements together.

Thel casing 9 is provided with an oil duct 19,A which registers with a similar duct 29 in the housing, it in turn registering with the oil passage 15 and bearing 12.

The shaft 3 carries a ange21, located laterally with respect to the bearing 12, the.

purpose of this flange being to throw off, by centrifugal force any oil that may leak onto that part of the shaft. The housing 16 is made to form an oil collecting chamber 22, immediately around this Harige. The shaft 3 may be provided with ordinary screw 'threads 23, cut in a. direction such as te1 throw any oil that may leali thereon, onto the flange 21. The oil collected in the cham- 'ber 22 escapes through suitable grooves and out through the loWeLoil ducts 20 and 19. The right hand Wallof the chamber 22 terminates just short of the threads 23, to give a slight clearance. The housing 16 may be A keyed to the casing 9 by pin 2e.'

The housing 16 is flanged, as at 25, to abut against thecasing 9. Vlhe other end of the housing is threaded to provide engagement for threaded cap 25a, which cap abuts the casing 9.

In assembling the parts the bearing is slipped on to the end 11 Aof the shaft; the two parts of the housing 16 are fastened in place therover, and keyed together; then the parts are inserted in the right hand end of the casing 9, after which the cap 25n is put on and screwed up to bring the fla-nge into tight engagement with the casing 9. The parts are thus assembled, keeping the ,casing 9 integral.

The other end 26 of theshaft is mounted in a. bearing 12 similar to bearing 12, butA` made in two parts this end of the shaft may carry the usual thrust flanges 27.
